What Is Metopic Craniosynostosis? Symptoms & Treatment Options
Written by Medicover Team and Medically Reviewed by Dr Madhu Mohan Reddy , Pediatric Surgeon
Metopic craniosynostosis is a condition where the metopic suture in a baby's skull closes too early, causing a visible ridge on the forehead and a triangular-shaped head. This can lead to developmental concerns if untreated. Understanding its causes, symptoms, and treatment options helps ensure timely diagnosis and proper care.
What is Metopic Craniosynostosis?
Metopic craniosynostosis is a congenital condition characterised by the premature fusion of the metopic suture, which is the growth line running from the top of the head down the middle of the forehead to the nose.
The early closure of this suture can result in a distinct ridge, known as a metopic ridge. It may result in a triangular-shaped forehead, a condition also referred to as trigonocephaly.
What are the Symptoms and Warning Signs of Metopic Craniosynostosis?
Metopic craniosynostosis is marked by a distinct abnormality in forehead shape due to early fusion of the metopic suture. Recognising these signs early helps guide timely diagnosis and treatment to prevent long-term complications.
Common Symptoms
- Visible metopic ridge on the forehead
- Triangular-shaped forehead (trigonocephaly)
- Closely set eyes (hypotelorism)
Severe Symptoms
- Developmental delays in severe cases
What are the Different Types of Metopic Craniosynostosis?
Metopic craniosynostosis typically manifests in varying degrees of severity, but it is generally categorised as a single-suture synostosis. It does not have different subtypes but may be classified based on severity:
- Mild Metopic Ridge: A noticeable ridge with minimal deformity
- Moderate to Severe Trigonocephaly: Prominent triangular forehead shape with potential orbital and neurodevelopmental impact
What are the Common Causes and Risk Factors of Metopic Craniosynostosis?
The exact cause of metopic craniosynostosis remains uncertain; however, researchers believe that both genetic and environmental factors contribute to its development. Identifying these risk elements can assist in early recognition.
Metopic Craniosynostosis Causes
- Genetic mutations linked to cranial development
- Maternal smoking during pregnancy
- Use of certain medications during pregnancy
Metopic Craniosynostosis Risk Factors
- Family history of craniosynostosis
- Environmental exposures in utero
- Male gender (higher incidence reported)

Get Second OpinionHow is Metopic Craniosynostosis Diagnosed?
Early diagnosis of metopic craniosynostosis allows for effective intervention. Diagnosis involves clinical assessment supported by imaging techniques.
Diagnostic Procedures
These assessments are crucial in determining the appropriate treatment plan.
What are the Treatment Options for Metopic Craniosynostosis?
Treatment aims to correct skull deformities and support normal brain growth. The choice of procedure depends on severity and the child's age.
Surgical Procedures
- Cranial Vault Remodelling: A traditional, open surgery performed between 6 to 12 months of age to reshape the forehead and orbit.
- Endoscopic Strip Craniectomy: A minimally invasive procedure where the fused suture is removed. Typically followed by helmet therapy to guide skull growth.
Post-Surgical Care and Monitoring
- Routine follow-up appointments
- Helmet therapy (for endoscopic patients)
- Monitoring of brain development and skull shape
When Should You See a Doctor for Metopic Craniosynostosis?
You should consult a pediatrician if your infant displays unusual head or forehead shape, especially a pronounced ridge down the forehead or closely set eyes. Early detection enables less invasive treatment and improved outcomes.

What is the Recovery Process After Metopic Craniosynostosis Treatment?
Recovery varies based on the surgical method used. Complete aftercare is essential for optimal outcomes.
Rehabilitation and Follow-up
- Helmet therapy may continue for several months after endoscopic surgery
- Physical and cognitive development assessments at regular intervals
- Ongoing imaging to track skull and brain development
Long-term Outlook
Most children treated for metopic craniosynostosis achieve normal developmental milestones with a good cosmetic outcome.
What Precautions Can Help Prevent Metopic Craniosynostosis?
Since metopic craniosynostosis may have genetic and environmental causes, complete prevention may not be possible. However, certain precautions may reduce risk.
Prevention
- Avoid smoking during pregnancy
- Avoid harmful medications or substances while pregnant.
- Genetic counselling for families with a history of craniosynostosis
Complications if Untreated
- Increased intracranial pressure
- Facial asymmetry
- Cognitive developmental delays
